Portico75 Build Guide

Here's our step-by-step walkthrough on how to put together a Portico75 keyboard. If you would like to watch a guide video click here to see Dutchmasters put together the Portico75.

To briefly summarize it, the steps are:

  1. Assemble and attach stabilizers to PCB.
  2. Screw together the PCB, plate, and felt dampening mat.
  3. Put these into the polycarbonate case and screw together.
  4. Insert switches and test that they work in VIA Configurator.
  5. Add on keycaps.
  6. Customize the keymap with VIA.

Before You Begin

Gather all the parts you’ll need, and make sure you have a clear surface to work on. We recommend having a few containers handy to place screws and such so they don’t get lost.

Download VIA Configurator, which you'll be using to test your switches.

Portico Parts

  • Polycarbonate Case – top and bottom
  • Plate
  • PCB
  • Knob
  • Screws
    • Gold screws for the case (x9)
    • Black screws for the standoffs (x10)
  • Standoffs (x5)
  • Silicon dampening mat
  • Felt dampening mat
  • Stabilizers (Portico uses three 2u stabs and one 6.25u stab)
  • Switches (x79)*
  • Keycaps*
  • USB-C cable
  • Protective carrying case

*Switches and keycaps are not included in the Portico Build Kit, and need to be bought separately.


  • Screwdriver
  • Allen key
  • Switch puller
  • Keycap puller
  • Tweezers (optional)


Portico75 will be packed in its protective carrying case. It will come assembled, and you'll need to disassemble it in order to install stabilizers.

First, disassemble your Portico.

  • Remove the knob from the front. (Slight turn to loosen)
  • Remove the 9 screws from the bottom, and store them somewhere secure.
  • Take out the top and bottom case. Note: Once taken apart, the top case will appear warped. This is normal and expected. Once screwed back together, it will be straightened.
  • Unscrew the standoffs and screws that are holding together the plate, felt mat, and PCB. Take care while doing this, as they're very small parts. Store the screws and standoffs in a safe container. There are 5 standoffs, and 10 black screws that go in them.
  • Take apart the PCB, felt mat, and plate.

Assemble and attach stabilizers

Next, you need to assemble and attach your stabilizers to the PCB. Portico uses three 2u stabilizers (Left Shift, Backspace, and Enter) and one 6.25u stabilizer (spacebar).

Assemble the stabilizers: (View a video tutorial here.) 

  1. Insert the stem up into the housing. The stem side with two holes should face outward where the wire will sit.
  2. Insert the wire into the housings. The wire should go into the bottom hole.
  3. Snap the wire securely into place.

Attach the stabilizers to the PCB. Stabilizers sit on the top side of the PCB, which is the flat side, and screw in through the bottom.

  • Locate the PCB holes. The switch positions are bracketed on the PCB. The keys that require stabilizers have extra holes on their left and right. The orientation of these (i.e. whether the smaller hole is on the top or bottom) can vary.
  • Optional: add the included stickers between the two stabilizer holes, to fit under where the housing sits. This is to help dampen the sound.
  • Align the stabilizer housings and attach them to the PCB. The screw should go into the smaller hole. The washer acts as a cushion between the screw and the PCB.

After attaching the stabilizers for the Left Shift, Backspace, Enter, and Spacebar, your PCB will look like this:

Put together the PCB, Plate, and felt mat

Screw the standoffs (x5) onto the PCB. The standoffs sit on the top side of the PCB and the screw goes through the bottom. Standoffs go in the four corners, and one goes in the middle.

Note: the standoffs and screws are very small. The screws go in quite shallowly, and are easy to knock loose. Take care when handling the PCB as to not drop anything.

Standoffs on the PCB

Screwing in the standoff to the PCB

Put the felt mat on PCB, and the plate on top of the mat. These line up with the PCB one way, so if something is misaligned, rotate or flip it over. You can align it by paying attention to the spacebar section and the right column of keys (a 1 x 5 column). The top of the plate is the side that says 'Portico.'

Screw together the plate to the PCB. The screws go through the top of the plate where the five standoffs are.

Put it all into the case

Now, we’ll assemble the polycarbonate case. Put the silicone mat into the bottom case. It only fits in one way—the hexagons face up, and the cutouts on the mat’s bottom edge match up to the screw holes on the edge of the case.

Put your Plate-Mat-PCB sandwich on top of the mat. The gaskets from the plate line up with the bottom case. The USB hub faces towards the back. 

Portico75 mounting system

Connect your plate to the USB hub. Using tweezers can help guide your wire into the port. Make sure the wire isn't twisted or it will be inserted upside down.

Put the top case on carefully so that it encloses everything. You might need to wiggle it into place.

Hold this all together firmly and flip it over to the bottom side. Screw together the top and bottom cases with the 9 gold screws.

Flip board over and install the knob. Gently tighten with Allen key.

Insert switches and test in VIA

Time to put in switches and test them! Plug your keyboard into your computer and open up VIA Configurator. You’ll be using this to test that your switches are registering keypresses.

  • VIA will automatically detect that the Portico75 is plugged in and compatible.
  • In the Key Tester tab, you'll see a standard keyboard layout. When you press a switch on the Portico that corresponds to a key, it will light up in the Key Tester. For example, when you press the top left key on the Portico, the Esc key in the Key Tester will light up to show that the switch is working.

Insert your switches. Portico75 uses 79 switches.

  • Before inserting each switch, check that the pins are straight. If a pin is bent, you can gently straighten it with a pair of tweezers.
  • Insert the switch straight down. The two switch pins match up to the switch pin holes in the PCB.

Troubleshooting: If your switch isn't registering, pull it out with your switch puller and check the pins on the bottom. It's easy to accidentally bend switch pins. You can gently pull it straight with some tweezers.

Add keycaps

Once you've confirmed all your switches are working, you can add on your keycaps! Portico is a 75% keyboard, which makes it easy to outfit with many keysets.

Congratulations 🎉 you've built a Portico keyboard! Take some glamor shots and share online, we’d love to see your builds if you tag us @thekey.company on Instagram. 

Customizing the Keymap

The default Portico layout can be adjusted in VIA Configurator

See high-res layout image →

You can adjust the RGB settings by holding down the Layer key (the key immediately to the left of the arrow keys on the bottom row) and pressing:

  • FN + F1: Effect mode increase
  • FN + F2: Effect mode decrease
  • FN + F3: Hue 1 increase
  • FN + F4: Hue 1 decrease
  • FN + F5: Saturation 1 increase
  • FN + F6: Saturation 1 decrease
  • FN + F7: Hue 2 increase (please note, only a few effects use a second color)
  • FN + F8: Hue 2 decrease
  • FN + F9: Saturation 2 increase
  • FN + F10: Saturation 2 decrease
